Syntax ARCCONF SETPERFORM Parameters Controller# is the controller number. Performance Mode is 1 (DYNAMIC/Default) or 2 (OLTP/Database). Example ARCCONF SETPERFORM 1 2 arcconf setpower Changes power management settings for disk drives on a controller or logical drive. Syntax ARCCONF SETPOWER Stayawake DISABLE| ARCCONF SETPOWER Spinup ARCCONF SETPOWER LD DISABLE|[SLOWDOWN ] [POWEROFF ] [VERIFY ] Chapter 2: Using the Command Line Utility . 22 Parameters Controller# is the controller number. Stayawake sets the stayawake period for the disk drives on the controller. During the stayawake period, the disk drives always operate at their peak spin rate. Disable is a keyword that disables the stayawake period for the disk drives on a controller. starttime specifies the beginning of the stayawake period, in the form HHMM (24-hour format). endtime specifies the end of the stayawake period, in the form HHMM (24-hour format). Spinup sets the spin-up limits for the controller—the maximum number of drives that the controller may spin up at one time. internal# is the maximum number of internal drives that the controller may spin up at one time, from 0-20. external# is the maximum number of external drives (such as the drives in a JBOD) that the controller may spin up at one time, from 0-20. LogicalDrive# is the logical drive number. Slowdown st# sets the disk drive slow-down timer, in minutes. Valid values are 0 (never), 3, 5, 10, 20, 30, 60, 120, 180. Poweroff pt# sets the disk drive power-off timer, in minutes. Valid values are 0 (never), 3, 5, 10, 20, 30, 60, 120, 180. Verify vt# sets the period of inactivity, in hours, after which an inactive drive (a drive that’s already powered down) is restarted to verify its operating condition. Once the check is completed, the drive is powered down and returns to its inactive state. Valid values are 0 (never), 1, 2, 3, 8, 12, 24. Note: For the Slowdown, Poweroff, and Verify timers, st# must be less than pt#, and pt# must be less than vt#. You can set one or more timers, in any order, in a single command. Keep in mind that the Verify timer, vt#, is specified in hours; the other two timers are specified in minutes.

Syntax ARCCONF SETPRIORITY [TASK ID] [current] Parameters Controller# is the controller number. Task ID is the number of the task to be changed. Use arcconf getstatus to obtain the task ID. Omit this parameter to set the controller’s global background task priority; that is, ...
